If you have any experience in woodworking, chances are you’ve heard of a “dado” cut. These specialized trench cuts are used for a variety of purposes, including building cabinets and bookshelves.
But dado cuts cannot be made with just any old saw blade. In fact, you actually need a specialized “dado blade” in order to get these important cuts just right.
Unlike most saw blades, not all table saws are designed to accept a dado blade set. As a result, woodworkers who intend to build wooden cabinets or shelves must plan ahead and purchase a table saw that can utilize dado blade sets safely.
If you’re planning to build either of these kinds of furniture or are simply looking to upgrade your wood shop’s capabilities, then you’ve come to the right place.
This article will take you through all of the basic information you need to know about dado blades and the table saws with which they are compatible.
Along the way, you’ll learn how to make a dado cut with a table saw, and also learning proper safety etiquette when using a dado blade on a table.
This article will even provide you with insights into the best table saws that accept dado blades on the market today.

What is a Dado Blade?
First, let’s start with the basics. A dado blade is a type of circular table saw blade used to cut dadoes.
These blades are sometimes arranged and installed in sets, depending on the type of dado that is being cut.
Dado blades typically come in two types, known as stacked blades and wobble blades, respectively.
Stacked Dado Blade
A stacked dado blade set can take on several different forms, depending on the user’s desired dado width.
However, they are typically composed of two circular saw blades affixed to either side of a removable chipper piece.
This composition makes it easier for the user to control the width of the dado cut while also smoothing down its base.
One notable downside of the stacked dado blade, however, is that it requires disassembly and the addition of spacers any time a wider dado cut is needed.
Wobble Dado Blade
Meanwhile, a wobble dado blade (also called an “adjustable dado blade”) is a specialized circular blade mounted on a multi-piece hub.
This hub can be adjusted while in use to create a greater angle for the attached blade to cut at.
This, in turn, allows the user to increase the width of their dado cut based upon the blade’s angle. However, some users do not favor wobble blades due to their inherent vibration while in use.
What is a Dado Cut?
A dado cut is considered one of the most basic woodworking joints available to amateurs and professionals alike.
Their basic composition consists of the squared, three-sided channel cut against the grain of a piece of wood.
This channel is typically made wide enough such that another piece of wood (such as a shelve) will fit snuggly into it.
Dado cuts come with a variety of practical benefits when implemented into a woodworking project.
For example, they offer a great deal of vertical sheer resistance due to the three-sided manner in which an inserted workpiece is captured by the cut.
Dado cuts are also less likely to wear down over time, given that they are primarily designed to hold an inserted workpiece entirely stable.
Dado cuts see a whole host of applications in the woodworking field. Most often, they are used in cabinets in order to create reliable shelving supports.
However, dado cuts also see use as drawer dividers and general-use partitions.
How to Make Dado Cuts with a Table Saw
Making a proper dado cut takes some practice, as well as the proper tools. But most woodworkers can learn how to do so efficiently, thus opening the door to more complex cutting maneuvers.
First, before starting the process of making a dado cut, a woodworker must equip themselves with the proper safety equipment (see below for more details).
Then, they must acquire a dado set of their own. These usually consist of a stacked set of regular blades and chipper blades.
Prospective dado makers must also obtain and attach a throat plate to a compatible table saw.
Next, you’ll need to determine your desired dado width. This will vary from project to project, depending on the cut’s intended purpose.
You can and should determine your dado’s width before cutting any wood, though. To do this, lay your workpiece flat on your work surface.
Then, stack your dado set-pieces flat on the surface beside it. Continue doing this until you have a desired set width.
Once you have your dado set properly arranged, you can mount it onto a compatible table saw and raise it to the desired cut depth.
Then, you should make a test cut or two to see if your set arrangement or depth needs to be adjusted. To keep your cut straight and even, use your table saw’s miter gauge attachment.

How to Safely Use Dado Blades
As with all types of woodworking, safety is the key to fully enjoying your experience, both in the short and long terms.
At a basic level, this means that you should always step up to your dado-compatible table saw wearing the right personal safety equipment.
In particular, you should always wear eye protection, ear protection, and properly fitted clothing whenever you decide to work with these rapidly-spinning power tools.
As for the dado blade set itself, there are a few tips to consider when it comes to safe use.
For example, the two circular blades in your set should always be positioned such that their teeth point outward.
In many cases, this can be done at a glance by ensuring that the marked side of the circular blade is facing outward.
Also, when arranging your dado set, be sure that each chipper blades’ teeth are slightly offset.
Not only does this cut down on unnecessary friction, but it can also ensure that the base of your dado’s channels is far cleaner and far smoother.
